Description

Technical Field

[0001] This invention belongs to the field of medical preparation technology, specifically relating to a medicinal diet to enhance immunity. Background Technology

[0002] Immunity is a vital defense mechanism for the human body, and medicinal cuisine, as a traditional method combining traditional Chinese medicine theory and dietary therapy, plays a unique role in enhancing immunity. With a history spanning thousands of years in China, medicinal cuisine is a treasure trove of traditional Chinese medicine. Guided by traditional Chinese medicine theory, it combines traditional Chinese medicine with traditional culinary techniques to achieve the goals of disease prevention and treatment, rehabilitation and health maintenance, and longevity.

[0003] As living standards improve, people are increasingly pursuing health and hoping to improve their quality of life through reasonable methods. Medicinal cuisine, with its unique advantages of "medicine and food sharing the same origin, simplicity, effectiveness, and affordability, integrating medicine and nourishment into food," is widely loved and favored. Traditional Chinese medicine, based on the concept of harmony between man and nature and a holistic approach, balances Yin and Yang, strengthens the body's resistance, and eliminates pathogenic factors. Medicinal cuisine emphasizes "preventive treatment," using a reasonable daily diet to prevent disease, which perfectly aligns with modern people's needs for disease prevention.

[0004] In existing research, patent document CN107692220A discloses a health-promoting medicinal diet that enhances human immunity. This diet consists of four different products prepared by adding any one of the following formulas: Formula A includes American ginseng, grape seed, Polygonatum sibiricum, Polygonatum odoratum, Ganoderma lucidum, Gastrodia elata, Pueraria lobata, Dendrobium officinale, Dioscorea opposita, black beans, and Panax notoginseng; Formula B includes Codonopsis pilosula, Angelica sinensis, Polygonum multiflorum, Cistanche deserticola, and Cordyceps sinensis; Formula C includes oats, wolfberry, Astragalus membranaceus polysaccharide, Acer truncatum seed oil, Rehmannia glutinosa, seahorse, Cistanche deserticola, and Cordyceps sinensis; Formula D includes Codonopsis pilosula, Angelica sinensis, Polygonum multiflorum, Rehmannia glutinosa, seahorse, Ginkgo biloba leaves, wolfberry, oats, Cistanche deserticola, and Cordyceps sinensis; and Formula E includes Codonopsis pilosula, oats, Astragalus membranaceus polysaccharide, seahorse, Ginkgo biloba leaves, and Rehmannia glutinosa. This medicinal diet consists of multiple ingredients, some of which are expensive, significantly increasing the cost of the diet. Furthermore, the diet requires preparation and formulation, making it unfriendly to the target consumer group.

[0005] For example, patent document CN116998722A discloses a health-preserving medicinal diet for replenishing qi and blood, including ginseng, lean meat, soybeans, red dates, black beans, yam, longan, angelica, astragalus, codonopsis, and white peony root. The weight ratio of lean meat, soybeans, red dates, black beans, yam, and longan is 1-3 parts: 2-3 parts: 0.5-1.5 parts: 1-3 parts: 0.3-1.3 parts: 0.1-0.3 parts, and the weight ratio of ginseng, angelica, astragalus, codonopsis, and white peony root is 0.2-0.8 parts: 1.5-3 parts: 1.5-3 parts: 0.5-1 part: 0.5-1 part. This medicinal diet combines traditional Chinese medicine with food ingredients to maximize the efficacy of the diet, not only regulating qi and blood and strengthening the body, but also improving immunity and delaying aging.

[0006] Medicinal cuisine is not only a food culture, but also a type of traditional Chinese medicine. Different medicinal cuisines have different target groups and health needs. Therefore, it is very necessary to develop medicinal cuisines with different effects to improve immunity for different target groups, so as to promote the development of medicinal cuisine and enable it to play a greater role in modern health care and meet people's diverse health needs.

[0027] Among the above-mentioned raw materials used in this invention, Platycodon grandiflorus, Astragalus membranaceus, Atractylodes macrocephala, Nelumbo nucifera, Lycium barbarum, Lilium brownii, Longan, Jujube and Tremella fuciformis are all food and medicine homologous substances, which enhances the safety of the whole formula as a medicinal diet.

[0028] The compatibility of traditional Chinese medicine (TCM) prescriptions emphasizes the rational selection and combination of herbs based on the specific condition to achieve the best therapeutic effect. In TCM theory, prescription compatibility follows the principle of "principal, assistant, adjuvant, and guide," which helps enhance the comprehensive synergistic effect of the herbs and improve clinical efficacy. For example, cinnamon twig combined with licorice can promote the transformation of yang with its pungent and sweet properties, while white peony root combined with licorice has a sour and sweet effect that transforms yin. These variations in compatibility can make the efficacy of the prescription far superior to that of a single herb. In practical application, the compatibility of prescriptions is not simply a matter of piling up herbs, but rather requires consideration of the pathogenesis, based on syndrome differentiation and treatment principles, and following theoretical principles of combination. This rigorous compatibility method allows for appropriate adjustments to the herbs, dosages, and dosage forms in the prescription according to clinical needs, adapting to the specific conditions of different patients.

[0029] In the medicinal diet of this invention, Astragalus membranaceus is used in the largest quantity and is the principal herb. It plays a role in replenishing qi and strengthening the exterior, promoting tissue regeneration and detoxification, and promoting diuresis and reducing swelling. It is used to treat symptoms such as qi deficiency and weakness, spontaneous sweating, and edema.

[0030] Fangfeng: dispels wind and releases the exterior, eliminates dampness and relieves pain, assisting Huangqi in treating symptoms such as spontaneous sweating caused by qi deficiency; Baizhu: strengthens the spleen and dries dampness, enhances the qi-tonifying effect of Huangqi, and at the same time treats symptoms of spleen deficiency and dampness. The two are in the same proportion and are combined as assistant herbs to assist Huangqi, enhance the efficacy, or target secondary symptoms.

[0031] Platycodon grandiflorus: Clears the lungs and soothes the throat, resolves phlegm and relieves cough, assisting Astragalus membranaceus in treating cough and other symptoms caused by qi deficiency; Lotus seed and lily bulb: Nourishes the heart and calms the mind, treating restlessness, insomnia, and other symptoms; Goji berry, longan, and jujube: Tonifies the liver and kidneys, nourishes blood and calms the mind, treating dizziness, vertigo, and insomnia caused by liver and kidney deficiency and blood deficiency; Tremella fuciformis: Nourishes yin and moistens the lungs, treating dry cough, dry mouth, and other symptoms caused by yin deficiency. The above-mentioned Platycodon grandiflorus, lotus seed, lily bulb, goji berry, longan, jujube, and tremella fuciformis are combined as adjuvant herbs, used to assist the principal and assistant herbs, or to target other specific symptoms.

[0032] Meanwhile, Platycodon grandiflorus, due to its lung-clearing effect, also acts as a guide in this medicinal diet, directing other drugs to the affected area.

[0033] This medicinal diet, through the rational combination of the above-mentioned herbs, nourishes qi and blood, strengthens the spleen and stomach, calms the mind and spirit, relieves fatigue, and enhances the body's immunity. Thus, on the one hand, it prevents the body from being harmed by the six pathogenic factors; on the other hand, even if pathogenic factors invade the body, the body's defensive qi can react quickly to expel them, preserving unaffected areas and preventing disease from developing before it occurs, thus preventing its progression once it has developed.

[0034] This medicinal diet formula integrates traditional Chinese medicine and modern nutritional theories, embodying the TCM concept of "medicine and food sharing the same origin." It combines medicinal herbs with food, offering both therapeutic and health-strengthening benefits, making it suitable for long-term use. The formula utilizes numerous substances that are both medicinal and edible, with a balanced combination of herbs and ingredients. This enhances the body's defenses while also considering the regulation of the spleen and stomach. As a medicinal diet, it is more readily accepted by the public than simple decoctions of Chinese medicine, especially for those who dislike the taste of Chinese herbs. This combination of medicinal and edible ingredients makes it easier to maintain long-term adherence.

[0035] The medicinal diet of this invention has a significant therapeutic effect on the related symptoms of patients with low immunity, and can increase the patients' hemoglobin, albumin and total protein content, promote immune function, enhance the body's resistance to disease, thereby achieving a significant improvement in immunity.
